Features of this Product

The SUPER AFC II is a fuel adjustment controller in which the airflow sensor signal or the p ressure sensor signal can be modified in a 12 point RPM range by 1% increments to increas e/decrease fuel in a range of ＋50% to −50%. The RPM to be corrected can be optionally se t in 200 RPM increments, and corrections can be made according to throttle opening amoun ts. In a turbo equipped vehicle with a hot wire type airflow meter, this controller provides a preventive function for engine stall due to blow-back during throttle return. The controller, which includes a knocking meter, allows the monitoring of knock levels check keeping the en gine under its optimum condition at all times. (Vehicle must have a factory knock sensor)

■Unconventional large screen monitor using a high-brightness VFD

The futuristic front face of this unit uses the large screen, high-brightness and easy to read VFD (Vacuum Fluorescent Display)

Use of the dot-matrix large screen monitor allows the displaying several types of information simultaneously. Display variations are not limited to only numeric value display, but also graph display, analog display, and other various displays are shown.

This allows the driver to recognize important information in an instant

■Utilizes a thin case and single button

A thin case of 52mm(L) × 126mm(W) × 18mm(D) (Minimum) has been achieved by op timization of the circuit board and case design. The product can be easily installed on t he steering column or dash board. Since there is no separate unit besides the main unit it is not necessary to secure a place for installing any separate unit. Using a 4-direction switch with a center pushbutton and a rotary switch gets rid of the button-to-button distance and permits quick operations, thereby providing efficient operation of the unit

■Battery-less memory that can keep initial setup data in the memory even if the vehicle battery is disconnected

With the use of the EEPROM, the initial setup data is not lost unless initialization is perf ormed, even if the power supply is turned off or the vehicle battery is disconnected. The setting data, such as peak value and correction value, is never lost. Accordingly, if the vehicle battery is disconnected for service inspection, initial setup and settings do not need to be performed again and the data history is not lost

！ CAUTION

●This product cannot be used for any application other than the vehicles mentioned in the separate Vehicle Specific Application Charts

●Note that noise interference may be caused to radio, TV, etc. depending on the mounting location of this product and the routing of the signal harness

●This product generates heat in the power ON status. This is not abnormal

6

■Storing two patterns of setting data in the memory

Two patterns of setting data including air correction factor, throttle opening, air correcti on engine revolution speed, deceleration air upper limit, etc. can be stored in the memory.

There are two files that can be stored in the memory. The setting data can be selected i n an instant according to each driving stage such as circuit driving, town driving, and wi nding driving. When driving on the same stage, two patterns of setting data can be com pared. These patterns of setting data can be used for various purposes

■Setting disable function by password

If the setting data or initial set points are changed by misoperation or mischief, the car c ondition may be deteriorated, or in the worst case, the engine may be damaged. In the S

AFC2 II, when the user sets a password optionally, changing the setting data or initial se tup items is disabled

■Warning function to make hazard known

It is possible to set warning values for the airflow using ratio, suction tube pressure, Kar man swirl sensor frequency, knocking, and engine revolution speed

When each item is set, the car condition can be precisely judged. The setting for the eng ine speed can also be used as a shift timing point

◆Knocking

Spontaneous ignition is caused by the heat and pressure of mixed air in the burning portion of non-combustion gas far from the plug and the heat of combustion chamber wall, so that the gas in the whole combustion chamber generates high-pressure waves momentarily. In this phenomenon, strong metallic noise is output from the engine unlike car knocking by which the car body becomes jerky, with the result that the valve is damaged and the piston is seized, thereby giving fatal damage to the engine.

As countermeasures, fuel adjustment, ignition timing adjustment, compression ratio adjustment, improvement of intake-side squish area, use of mirror type combustion room wall, and profile improvement of the exhaust-side cam shaft can be mentioned

！ WARNING

●During driving, the driver must not operate this product in any case

It will interfere with driving operations or result in an accident

●On general public roads, observe the road and traffic law to drive the car carefully

Air correction factor setting (Throttle opening, large/small)

In the SAFC, the input

airflow signal

is converted into an

air volume value

and this value is corrected by the

air correction factor

. As an output signal, the corrected

air volume value

is converted back into an

airflow signal

and then this signal is output to the electronic control unit (ECU).

Accordingly, supposing that the correction factor is +10%, the ECU recognizes that the air volume has increased 10%, so fuel is increased about +10%.

For air correction factor setting, the air correction factor can be adjusted by 1% increments in the correction range of +50% to –50% for each engine RPM at 12 points. It can also be set according to the throttle opening level

What to do in such a case ?

Fault related to the power supply

●Check if the battery is connected

●Check if the vehicle ECU harness is securely connected to the signal harness

●Check if the signal harness is connected to the connector of the SAFC main unit cable

Even if the connection is properly made, the power supply may not be turned on because of a contact defect. Check the plug and splice caulking portion once again

●The power supply is turned off because of vibrations

This may be due to a wiring contact defect

The display is not normal

●Each signal is not displayed (monitored)

Check if the harness connecting position is correct.

Install the harness by referring to the Wiring diagram by model attached to this product, taking special care about the direction of the ECU, and checking the connector shape and the number of pins

●The revolution speed display is not normal

・Check if the number of cylinders is correctly is set

・Genuine tachometers have a slight error. Even when a deviation of 200 to 300 rpm occurs at a highspeed revolution, this is normal. The numeric value of this product is a correct revolution speed

●The throttle opening display is not normal

・Check if the throttle sensor type has been set

・Check if the throttle opening has been learned

・For a vehicle without throttle opening signal, the throttle display cannot be performed

●Throttle opening Hi/Lo cannot be selected

Check if the throttle type is not set to ＊＊ If it is set to ＊＊ correction is not made by throttle opening, so the Hi/Lo map cannot be changed over

●The pressure display does not move

・For an airflow car (Hot Wire, Flap or Karman), the pressure display does not move.

For a pressure sensor type car only, the pressure display can be monitored
